Note: SATIS (the trademark) is spelled all caps except in “Satis Vacuum” (the name of the company) ((Draft)) SATIS AR coating technology Today, apart from quality and reproducibility, cost is moving to the top of the list of critical factors in the production of antireflection coatings. In this respect, too, Satis Vacuum has succeeded in the redefining the industry benchmark. Cost savings of unprecedented magnitude have been achieved with the new box coater generation – the 1200 DLF/TLF – and with dramatic process improvements. The following objectives were pursued: • Optical quality (bandwidth and residual reflection) In the interest of a genuine partnership, the policy at SATIS is to draw our customers’ attention to disparate process characteristics and different process optimization approaches. This is the only way to build a process portfolio that best matches each customer’s needs with respect to quality and productivity. And for this reason, it is necessary to individually qualify SATIS AR processes. SATIS AR coatings IONCOTE ZB-M/L CV FAST By improving the AR stack, this new SATIS process makes it possible to provide varnished plastic lenses with previously unattained levels of wear resistance and durability. For this purpose, a new hard buffer layer as well as intermediate plasma treatments were incorporated in the classic AR layer package. It is completed with a newly developed, easy-to-clean top coat. The result is an AR coating with significantly higher wear resistance than classic AR stacks and the added advantage of improved layer bonding. This new AR process was exhaustively tested with conventional ophthalmic lens substrates as well as all major lens and hard varnish brands. Independent experiments at the COLTS test laboratory in the USA demonstrate a genuine enhancement of wear and scratch resistance as well as bond strength. This coating can also be applied to glass lenses in the same vacuum cycle. Additionally, the deployment of the new 1200 DLF/TLF box coater generation increased productivity by up to 50%. The bottom line is a cost reduction per coating of as much as 30%. This establishes a new price/performance ratio benchmark for extremely discerning and quality-conscious customers. (Illustration of coating structure and reflectance curve. We might have a bar chart here, too. I don’t have any visuals or graphics to send you) Performance – ML FAST This classic SATIS process has been improved yet again. Despite perceptibly shorter cycle times, the coating is more durable. This AR coating is ideal for varnished plastic lenses as well as for glass lenses. It is the process of choice for customers who place emphasis on cost reduction while safeguarding the good to very good quality of the coating. (Reflectance curve) Multiquartz Z-P FAST This process has been optimized with regard to optical quality and handling convenience on the production floor. The coating is particularly suitable for mixed batches of varnished and unvarnished plastic Rx lenses. Short cycle times also optimize the price/performance ratio of this process. (Reflectance curve) Differences between basic SATIS AR coating processes q IONCOTE ZB-ML FAST: optimized for superb wear resistance on varnished lenses, durability, and good optical quality. q Performance – ML FAST: optimized for high wear resistance and extremely short cycle times. q Multiquartz Z-P FAST: optimized for handling convenience and extremely short cycle times as well as good optical quality. It has been verified that if the standard deviation for the lab points of residual reflection is s = ((complicated equation)) < 1.0 units during the SATIS acceptance test of a process in the commissioning phase, real-world stock lens coatings can be conducted with s < 1.4 units as long as SATIS cleaning and calibration instructions are followed. This was the result of a recently conducted case history covering the Rx lens inventory of a major ophthalmic lens manufacturer. Apart from regular cleaning and autocalibration according to SATIS specifications, no other interventions are required to achieve this result. This confirms that SATIS’ many years of experience in customized process development have yielded remarkably stable coating products. SATIS is determined to safeguard its leadership position in process and coating quality. (The customer has a comparison table and pictures of box coaters)
